Definitions

  • a main battery for high voltage which uses a main voltage of 250V or more and a subsidiary battery for a general vehicle which uses a voltage of 12V.
  • the main battery for high voltage supplies a specific amount of power to a driving system, air conditioner, and heater in the hybrid electric vehicle.
  • the subsidiary battery which supplies a voltage of 12V supplies power to various types of electric/electronic assemblies as in the system of a general commercial vehicle.
  • such a hybrid electric vehicle uses a subsidiary battery having a voltage of 12V.
  • the subsidiary battery is charged using a Low voltage DC-DC Converter (LDC) for converting high voltage into low voltage.
  • LDC Low voltage DC-DC Converter
  • the cause thereof is determined using the vehicle controller 300 .
  • the vehicle controller 300 determines that power is not being smoothly supplied from the low voltage battery 420 to the braking device 200 .
  • the vehicle controller 300 determines that an abnormality has occurred in the low voltage DC-DC converter 100 .
